PWM on dspic33EP512MU810 MCU not working

Hello, 
 
 I am struggling to get the independent mode of PWM working on my dSPIC33EP512MU810 MCU. 
 
 I am using the PWM4H/L pins. 
 
My code as per below, Pin configuration seems ok, if I turn those PIN as GPIO, works fine. 
 
Any help would be appreciated. 
 
 

void pwmInit(void)
{
        
    ANSELEbits.ANSE6 = 0;
    ANSELEbits.ANSE7 = 0;
    TRISEbits.TRISE6 = 0;
    TRISEbits.TRISE7 = 0;
    
    PTCONbits.PTEN = 0;
    
    PTPER = 499; 
    PTCON2 = 0;
    PHASE4 = 0;
    SPHASE4 = 0;
    PDC4 =5555;
    SDC4 = 5555;
    
    DTR4 = 0;
    IOCON4 = 0x8C00; 
    PWMCON4 = 0x00;
    FCLCON4bits.FLTMOD = 3;
  
    
    PTCONbits.PTEN = 1;
}

void main()
{
 pwmInit();
}

 
 
Thanks
